front suspension question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

i have a 72 gmc 2wd 3/4 ton. does anyone know if there is a five lug rotor that will fit in place of my 8 lug ones. or even a rotor and spindle combo that will bolt to my A arms? I have a nice set of five lug wheels, (5x5 and 5x5.5 bolt patterns) a new rear axle is easy, but i'm curious what parts i can put on the front without having a wider track width like the 73-87 trucks, thanks.

Without changing the a-arms and spindles you will not be able to get a 5-lug rotor to work. ECE does sell a spindle conversion kit that utilizes your existing 3/4 ton a-arms/ball joints and allows you to either install a 5 or 6 lug rotor. Your'e probably better off finding a 71 to 87 1/2 ton and grab the front suspension setup, brakes and all. In the long run replacement parts will be easier and cheaper to find....

good luck!

thanks 68jimmy, i read on another thread that the 73-87 have a different track width, and that i would have to use the a arms from those years too if i went that route. anyone know few parts i can use from the newer trucks?

I remember seeing conversion vans in the 80's which had the 20 badge for 3/4 ton but with 5 lug rims. Don't know if those would work? Anyone know? Never into vans, just thought it odd.
